Steam injection and inlet fogging in a gas turbine power cycle and related method |
摘要 |
A steam injection and inlet fogging system is provided for a gas turbine power plant that includes a gas turbine having a compressor, a combustor and a turbine for driving a generator. A waste heat recovery unit is arranged to receive exhaust gas from the turbine, the former having a plurality of heat exchange sections for heating water with the exhaust gas. A flash tank is arranged to receive heated water from the waste heat recovery unit for producing steam. A first stream of makeup water from a first of the plurality of heat exchange sections is flashed to the flash tank to also produce saturated steam and water at a first location in the flash tank. A second stream of water from a second of the plurality of heat exchange sections is also flashed to the flash tank to produce saturated steam and water at a second location in the flash tank. A portion of the saturated steam produced in the flash tank is supplied to the gas turbine combustor, and a remaining portion of the saturated steam is supplied to the compressor via an inlet fogger. The system also controls contaminants in the water produced in the flash tank.
